Definitions

  • This invention relates to the enhancement of bleaching compositions that are substantially devoid of peroxyl species.
  • the shelf life of a product may be regarded as the period of time over which the product may be stored whilst retaining its required quality.
  • a satisfactory shelf life is in many instances a crucial factor for the success of a commercial product.
  • a product with a short shelf life generally dictates that the product is made in small batches and is rapidly sold to the consumer. It is also a concern to the owners of a brand with a short shelf life that the consumer uses the product within the shelf life otherwise the consumer may be inclined to change to a similar product of another brand.
  • a similar product with a long shelf life may be made in larger batches, held as stock for a longer period of time and the period of time that a consumer stores the product is not of a great concern to the owners of a particular brand.
  • UV irradiation Ultraviolet radiation is found in irradiation from the Sun and artificial lights.
  • the present invention provides a liquid bleaching composition comprising:
  • liquid bleaching composition is stored in a container, the container absorbing incident UV irradiation and reducing the amount of UV irradiation passing through the container upon exposure of the container to the incident UV irradiation.
  • the term "substantially devoid of a peroxygen bleach or a peroxy-based or peroxyl-generating bleach system” should be construed within spirit of the invention. It is preferred that the composition has as low a content of peroxyl species present as possible. It is preferred that the bleaching formulation contains less that 1 % wt/wt total concentration of peracid or hydrogen peroxide or source thereof, preferably the bleaching formulation contains less that 0.3 % wt/wt total concentration of peracid or hydrogen peroxide or source thereof, most preferably the bleaching composition is devoid of peracid or hydrogen peroxide or source thereof. In addition, it is preferred that the presence of alkyl hydroperoxides is kept to a minimum in a bleaching composition.
  • the present invention also extends to a commercial package together with instructions for its use.
  • the container absorbs UV irradiation and reduces the incident UV irradiation on the container passing through to the contents held within. It is preferred that the container absorbs strongly in the range 220 to 400 nm, most preferably 290 to 320nm. The amount of UV irradiation in everyday situations will depend upon whether the irradiation is direct sunlight light from artificial lighting.
  • the container may have an amount of UV absorbent material incorporated into it such that the UV absorbent material is integral to the container.
  • the container is sheathed or has a coating such that the sheath or coating absorbs incident UV irradiation.
  • the container is substantially uniform in its absorption of UV irradiation. That is to say, that there is no area of the container that permits UV irritation to pass through to the inner surface of the container as defined herein.
  • any top that is used to cap/seal the container is also UV absorbent as defined herein.
  • Another approach to stabilising the liquid bleaching formulations is to incorporate a material that absorbs UV irradiation into the liquid per se.
  • a material that absorbs UV irradiation is one that quenches in an intramolecular manner.
  • the bleach catalyst per se may be selected from a wide range of transition metal complexes of organic molecules (ligands) .
  • the level of the catalyst in a commercial bleaching composition is from 0.0001 to 0.6 wt/wt %, preferably 0.001 to 0.15 wt/wt %, most preferably 0.01 to 0.1 wt/wt %. We have found that the level of catalyst is optimum between 0.03 to 0.09 wt/wt % in the commercial bleaching composition.
  • the level of the organic substance is such that the in-use level is from 0.05 ⁇ M to 50 mM, with preferred in-use levels for domestic laundry operations falling in the range 1 to 100 ⁇ M. Higher levels may be desired and applied in industrial textile bleaching processes. A mixture of different catalysts may be employed in the bleaching composition.

  • WO00/29537; WOOO/52124, and WO00/60045 the complexes and organic molecule (ligand) precursors of which are herein incorporated by reference.
  • An example of a preferred catalyst is a transition metal complex of MeN4Py ligand (N,N-bis (pyridin- 2-yl-methyl) -1, 1-bis (pyridin-2-yl) -1- aminoethane) .
  • the ligand forms a complex with one or more transition metals, in the latter case for example as a dinuclear complex.

  • Rl and R2 are independently selected from: Cl-C4-alkyl, C6-C10-aryl, and, a group containing a heteroatom capable of coordinating to a transition metal;
  • at least one of Rl and R2 is the group containing the heteroatom. Most preferably at least one of Rl and R2 is pyridin-2-ylmethyl .
